Objective To establish a assessment system for comprehensive clinical competency of general practice residents.Methods An assessment system for comprehensive clinical competency of general practice residents was developed with modified Delphi expert consultation during November 2010 to October 2011.Thirty three experts in clinical practice,education and administration of general practice were invited for two-round Delphi questionnaire consultation.Results In two-round consultation,the expert activity coefficient was 100％,the authority coefficient was 0.852 and 0.855,and the coordination coefficient for the importance of the indicators was 0.228 and 0.245 respectively (P =0.000).The opinions among the experts became consistent from round 1 to round 2.An assessment system was established,which consisted of 5 first-level (professionalism,communicate skills,clinical competency and professional development ability) and 36 second-level indicators.Conclusion The index system established in this study may be used as references for evaluating comprehensive clinical abilities of general practitioners systematically and objectively.

BACKGROUND:Atopic individuals predispose to alergic rhinitis after contacting with an alergen, which is mainly released by IgE-mediated histamine. Alergic rhinitis is a kind of non-infectious inflammatory disease that involves a variety of immune cels and cytokines and is related to Th1 and Th2 immune imbalance. Interferon γ is a cytokine secreted by Th1 cels, while interleukin-4 is a cytokine secreted by Th2 cels. OBJECTIVE:To establish a stable 129Sv mouse model of alergic rhinitis, so as to lay the foundation of establishing gene knockout 129Sv mouse models of alergic rhinitis, and to observe the concentration variation of IgE, interleukin-4 and interferon γ. METHODS: Twenty-four mice were randomly divided into 2 groups: model and control groups. Mice in the model group were sensitized by intraperitoneal injection of ovalbumin to establish mouse models of alergic rhinitis. Mice in the control group were subjected to intraperitoneal injection of PBS. After successful modeling, pathological changes of nasal eosinophils and plasmocyte infiltration were evaluated by nasal mucosa staining. Interleukin 4 and interferon γ levels and ovalbumin-specific IgE antibody concentration were detected by enzyme-linked immunosorbent assay. RESULTS AND CONCLUSION:Enzyme-linked immunosorbent assay showed that compared with the control group, serum ovalbumin-IgE and interleukin-4 concentrations were significantly increased, and Interferon γ concentration was significantly lower in the model group (P < 0.05). Hematoxylin-eosin staining results showed that cilia lodging and submucosal serous gland hyperplasia, eosinophils and plasmocyte infiltration were obvious. These results confirm that a mouse model of allergic rhinitis was successfully constructed in this study and the pathogenesis of allergic rhinitis was related to Th1/Th2 imbalance.

Thirty four residents of general practice and 11 students of junior college to undergraduate program were evaluated with the mini-clinical evaluation exercise (mini-CEX) when they were rotated to community clinics or the ward of general practice in Zhongshan Hospital from September 2009 to February 2010. The reliability and validity of mini-CEX for rotation examination in general practice training was assessed. Forty five trainees and 9 clinical faculty members completed 81 mini-CEX evaluations. The Cronbach's alpha coefficient was 0. 932. Criterion-related validity for mini-CEX overall competence with the end examination of rotation was O.53 ( P ＜ 0.001 ). The results indicate that mini-CEX may be an appropriate evaluation tool for rotation examination in general practice training.

Objective To develop an assessment criteria for general practitioner (GP) trainers in clinical training base.Methods Based on the extensive literature review and expert interview,a preliminary index system was established with 4 first-grade indicators and 45 second-grade indicators for GP trainers in clinical training base.During 2012 to 2013,a two-round Delphi consultation was conducted to establish the assessment criteria.Results Thirty seven experts engaged in clinical practice,training and managers of GP training program from clinical training bases,medical schools,or health bureau in Shanghai were invited for Delphi consultation.Among them 64.8 (24/37) ％ were engaged in GPs training over 5 years,78.4％ (29/37) worked as GP trainers,70.2％ (26/37) with high-level professional title.In two round consultations,the activity coefficient of the experts were 97.3％ and 100.0％,authority coefficient were 0.817 and 0.855,and harmonious coefficient of importance of the evaluation were 0.188 (P ＜ 0.01) and 0.278 (P ＜ 0.01),respectively.The opinions among the experts were consistent from the first round to the second round.The assessment criteria for GP trainers in clinical training bases was established with 4 firstgrade indicators and 27 second-grade indicators.The 4 first-grade indicators were professionalism,clinical practice components,teaching quantity & components,basic conception of general practice,with weight coefficient of 0.253,0.253,0.251 and 0.243,respectively.Conclusion The established assessment criteria for GP trainers is credible and comprehensive,which can be applied in evaluating the comprehensive capacity of trainers in clinical training bases.

Objective To study needs of training of trainers(ToT)in mini-clinical evaluation exercise(mini-CEX)and its effectiveness.Methods One hundred and fourteen doctors involved in TOT for mini-CEX were interviewed with questionnaire before and after training for their satisfaction of training and fifty of them scored the training videos.Results Before the training.39%(44/114)of doctors involved in TOT knew mini-CEX and 97%(111/114)of them hoped to know how to carry out mini-CEX thronsh training.When the training finished,30%(34/114)tO 55%(63/114)of them could completely understand seven items of examinations of mini-CEX.Fifty doctors involved in TOT scored the training videos after the training.There was signifieant difference in scores between TOT and standard scoring on training video 1 for teaching of coronary heart disease and video 2 for teaching of hematochezia(P<0.05).No significant difference Was found in scores between TOT and standard scoring on the video 3 for teaching of abdomihal pain(P>0.05).as well as those between TOT with five or less years experience and those with more than five years experience(P>0.05).Conclusions Currently,doctors involved in TOT have more demands on mini-CEX.However,effectiveness of short-course training for mini-CEX is not satisfactory,and pattern of its training should be improved further.

Objective To study the association between endometrioid uterine carcinomas and metabolic syndrome (MS). Methods A retrospective study was conducted on 123 patients who were admitted in Department of Gynecology Oncology, Zhejiang Cancer Hospital (study group) and 90 healthy women (control group) with matching age from Jan. 2005 to Mar. 2009. The general conditions[including age, whether menopausal, body mass index (BMI)];the risk factors for MS [including waist circumference,fasting plasma glucose, triglycerides(TG), high-density lipoprotein (HDL) and systolic and diastolic blood pressure]were analyzed. The clinical stage, histological type, and pathology differentiated degree of study group with or without MS were also analyzed by univariate analysis and Cox proportional hazards models.Results (1) The univariate survival analysis shown that there were no significant difference with age in two groups[(54.3±0.6) vs. (54.2±0.9) years;P>0.05], while the rate of menopausal, BMI(≥25 kg/m~2), the cases coupled with MS, the size of waist circumference (> 80 cm), the level of fasting plasma glucose (≥5.6 mmol/L),TG(> 1.7 mmol/L)and abnormal systolic and diastolic blood pressure in study group were higher than those in control group (67.5% vs. 48. 9%, 45.5% vs. 23.3%, 43.9% vs.18.9%, 50.4% vs. 27.8%, 53.7% vs. 21.1%, 40.7% vs. 21.1% and 40.7% vs. 25.6%,respectively, all P <0.05). The percentage of HDL(< 1.30 mmol/L) was higher in study group than that in control granp(63. 4% vs. 32. 2%, P <0.05). (2) There were not significant difference for the clinical stage, pathological type, grades between patients with or without MS in study group (P > 0.05). (3) The Logistic multivariate survival analysis shown that central obesity, higher TG, lower HDL and abnormal plasma glucose were independent risk factors for endometrioid uterine carcinomas coupled with MS (P< 0.05). Conclusion Metabolic syndrome is marginally associated with an increased risk of endometrioid uterine carcinomas, which may be the new point to screen, prevention and treatment endometrioid uterine carcinomas.
